Cat. No.	Z102405
Name	Recombinant Human IFNA4 (E. coli)
Description	All known subtypes of IFN- alpha show the same antiviral antiparasitic, antiproliferative activities. IFN-alpha forms are produced by monocytes/macrophages, lymphoblastoid cells, fibroblasts, and a number of different cell types following induction by viruses, nucleic acids, glucocorticoid hormones, and low-molecular weight substances. All IFN-alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha subtypes differ in their sequences at only one or two positions. IFN-alpha and IFN-beta are thought to bind to the same receptor. Signal transduction mechanisms elicited after binding of IFN-alpha to its receptors involves tyrosine phosphorylation (see also: PTK; protein tyrosine kinase) of various non-receptor tyrosine kinases belonging to the Janus kinases.

How do I choose the right growth factor for my experiment?

Cell type: Different cells respond to different growth factors. Choose a growth factor that promotes the growth or differentiation of your target cell type.
Desired outcome: Whether you are studying proliferation, differentiation, or survival, different growth factors will promote different cellular behaviors.
Concentration and formulation: Different experiments may require varying concentrations of growth factors.

	What is the shelf life and storage condition of this product?
	The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
